I say "Fix" because this is more of a temporary workaround until an official fix can be made. And, as always this worked for me, but YMMV.

The Short Version:
Disable Facebook syncing in email+accounts (I'm not talking about any app. This is the account setting under Settings > email+account that feeds the People Hub).

The Long Version:
I have had my Lumia 920 since 1/2/2013 and it has been randomly freezing up on me through out the day. It would freeze up during charging at night, either on the charging pad or plugged into the USB charger. It would freeze up randomly during the day after I had locked it. It never froze while I was actively using it, but, it was always a crap-shoot if it would turn on. Every time it froze I would have to do a soft reset (volume down + power button for 10 secs). I would say it froze about 2-3 times a day, sometimes more.

I tried a lot of the suggestions on this forum: turn off wifi, turn off bluetooth, hard reset the device, turn off background processes, etc. Nothing seemed to work. I opened a twitter dialog with @NokiaCareUS and they had me do everything I just mentioned. The last thing they wanted me to do was hard reset it and install my apps one at a time and see which one might be causing the issue.

So, I did this, and I went a little more drastic. I hard reset it and then left everything default for a day. The only thing I added was my Microsoft account so that my contacts and text messages would sync. My phone stayed running for 3 days with no freeze up (that rules out hardware issue). I then added my email syncing and added my Facebook account to email+accounts. That did it. Sometime overnight my phone froze and the alarm didn't go off again (I had a backup device this time ).

I wasn't sure what did it, email or Facebook syncing, so I disabled one and then the other. As it turns out, the Facebook syncing was causing it. Since I have disabled Facebook syncing, no freeze ups.

I have probably just jinxed it but it has been two days now without a freeze so it is promising. Can anyone else test this theory and see if it works for them?

My freezes have always been during or just after (mainly) wireless charging. I have not had any freezes if I disable wifi during charging.
Now I have deleted my Facebook account from the phone (not using it anyway). Will do an overnight wireless charge with wifi enabled - and see what happens ...

EDIT:
No freeze on first night. Will continue testing ...

My official fix for random freezing is by returning or exchanging the phone. I understand random freezes like once in a blue moon, but it should not be happening on a weekly/daily basis/even monthly basis.

I understand this is a post to help resolve the freeze issue specifically, but does anybody really want to go through all this when freezing happens on their phone when it shoulnd't be?

Totally agree. We had 1 out of 2 phones freeze and reboot. Replaced it and both perform perfectly without issues.

I replaced one that froze every hour or so. It would even freeze during set up--so I know that it wasn't a "rogue" app. The replacement hasn't frozen once in two weeks!

I would agree. If it was my wife's phone it would have gone back the next day and I was ready to take it back myself. Deep down the software developer in my was intrigued to find the issue. When I ruled out the hardware as the issue I knew it was something I was doing.

I was also a little skeptical taking it back because there were a bunch of posts on here about people having the same issue with a new phone.

Do you have Facebook setup in People Hub and it's not freezing?

[xsonwong]

Hope you can have longer test to prove it is the root cause :)

Once you found that, ask Nokia and Microsoft to fix it!!

However, I doubt why only some 920 have this problem but not other phone...

Quick update:
Still working well. No freeze after I deleted my Facebook account from the phone ...

EDIT:
Frooze again ...

POSSIBLE SOLUTION - I had freezing once/day first week & was about to return mine for exchange (I LOVE THIS PHONE!), but a fellow WP user told me all I needed to do was eject the SIM card & re-install firmly (as if the SIM card was not in well enough). I did it, skeptically, and proceeded to TRY to get the phone to freeze - I had about 12 apps running at once + IE, everything. It wouldn't freeze and hasn't in 2 days! I have about 5 more days in my 14 day exchange window with AT&T, so I'm hoping the SIM issue fixed it. (Sounds too simple to be true, but so far,so good)...

This guy is right!!! It's the SIM, and I'm guessing it's because the SIM card is not a proper one but a full sized one cut into a micro SIM.
It was freezing every 5seconds, I enabled flight mode and it's fine now! Spread the word people, it's the SIM.
